Male 43 been getting chest pain for 18 months. All blood tests, stress tests and echo cardiogram show no cardiac disease. Was sent for Cardio CT scan two weeks ago and results now back showing all clear cardio wise but noted 'two small biliary cysts noted'. Phoned GP today who had also had copy of letter and told to ignore bit about cysts as it said that they were small. Is this correct info or should they investigate further?
